Abstract

The invention provides an automobile suspension DMU (diesel multiple unit) model parameterization design method. A hard point meter is used for driving point and line models of all components of a suspension, a point and line DMU model of the suspension is built by using the point and line models of the components, the point and line DMU model drives the suspension components to move, and a DMU model of a suspension system is formed. When the method provided by the invention is implemented, during the design change on hard points, the DMU model of the suspension system can be changed only through changing the hard point meter, during the design change on the component structure, new components are used for replacing the original components, the re-building of the DMU model is not needed, the response time on the DMU checking after the design change is obviously shortened, and the workload of engineers is reduced.

Description

technical field [0001] The invention relates to the field of digital design of automobiles, in particular to a parametric design method of a suspension DMU model. Background technique [0002] In the automobile design stage, DMU model technology is often used, where the DMU is the abbreviation of Digital Mock-Up. Through the DMU model, a realistic computer simulation can be carried out on the product, which covers the entire life cycle from product conceptual design to maintenance service. Through the DMU model, the data of subsystems such as the suspension, steering, sub-frame, brake, drive shaft, and various soft and hard pipelines of the car can be debugged and simulated at various stages, such as installation / disassembly and static and dynamic interference checks. Give guiding opinions on the specific structural improvement of risky components, discover component interference problems in the design stage, and promote the improvement of these problems, thereby reducing d...
